King Narmer’s Macehead at the Ashmolean Museum, Oxford,  records the capture of 120,000 prisoners, 400,000 captive oxen, and 1,422,000 goats. I. Bernard Cohen in The Triumph of Numbers: “Perhaps the numbers are exaggerated, but we can, even so, learn from this object that the ancient Egyptians were able to write very large numbers.” See here for the specific Hieroglyphs.
